Paralysis is defined as complete loss of strength in an affected limb or muscle group. Paralysis may affect an individual muscle, but it usually affects an entire body region. The distribution of weakness is an important clue to the location of the nerve damage that is causing the paralysis. Words describing the distribution of paralysis use the suffix "-plegia," from the Greek word for "stroke."
The types of paralysis are classified by affected region --
1. Monoplegia, affecting only one limb
2. Diplegia, affecting the same body region on both sides of the body (both arms, for example, or both sides of the face)
3. Hemiplegia, affecting one side of the body
4. Paraplegia, affecting both legs and the trunk
5. Quadriplegia, affecting all four limbs and the trunk
